Ms Zhuang, a Hotel Test Sleeper, checks the bed of a business chain hotel in Beijing March 6, 2012. Zhuang was selected as one of three final winners out of 7,800 candidates and started working for Qunar as a Professional Hotel Test Sleeper in March 2010. At present, she has slept at more than 200 hotels. "My job is to role-play travelers of different types, different ages and genders at different scenarios, and see how each hotel fits their particular needs." Zhuang said. Her reviews help travelers make smart hotel picks and bring them a more pleasant experience on the road. Qunar, a Chinese online travel platform, started to recruit Professional Hotel Test Sleepers in 2010. The requirement for this new profession is to sleep at selected hotels without disclosing their real job and write expert reviews about the facilities, location, dining, services and prices of the hotels, in order to provide an independent third-party evaluation and an authoritative guide to travelers, according to the company.
